INQUIRER: A group of local investors will rescue the city’s trailblazing wireless network from what seemed like imminent shutdown, with a new for-profit company that will replace Earthlink Inc. as the system’s operator, according to multiple sources close to the deal. Although the details of the deal were unclear yesterday, the new company is said to be considering an advertising-based business model that would provide free Internet access to all, or at least in those places where the spotty network is available. Earthlink charged $20 a month for the service. The sources said little, if any, taxpayer money would be used in the deal, which is expected to be formally announced at a noon City Hall news conference today. MORE
